I T all whom it may concern:

Be it known that I, WILLIAM GUs'rAvUs Dn AREsr, a citizen of the United States, and a resident of Metuchen, in the county of Middlesex and State of- New Jersey, have invented certain new and useful Improve ments in Wall Constructions, of which the following is a specification.

The present invention relates in general bond with the tile or brick. Again, as it is I essential to strength,-the brick facing em bodies at regular intervals header courses.

In order to properly organize the tile with the ordinary courses and with the; header courses of the brick facing a peculiar construction and arrangement of the tile is necessary. This construction and arrangement as heretofore proposed has been such as to prevent the air passages through the tile from being continuous and also to preclude. the use of the full load bearing strength of the burned clay comprising the tile, so that the tile constitutes a dead load or weight.

As a consequence of. these features serious objections and disadvantages are met with for in the-first instance the rain and other moisture which penetrates the wall due to the low character of the bond between the mortar and the elements of the wall find its way into the interior of the building and works serious damage and finally the dead weight or load of the tile necessitates additional steelframeworkto support the same.

One of the principal objects of'the present invention is to overcome these disadvantages and objectionable features by providing a composite wall construction in which the tile and brick facing are properly organized to, obtain a high degree of strength and in such manner as to provide continuous air passes through the tile so as to arrest and dissipate the moisture finding its way into the wall and prevent the moisture from penetrating through the wall into the interior of the building; full load bearing strength 0 the burned clay comprising'the tile. is taken advantage of and utilized to sustain the building con described and construction.

in which the stru'ctionto thereby reduce the amount of man srAras rjArr mr comm,

steel framework necessar and in which the tile of-the wall is of simp e and durable con.-

struction, easy and inexpensive to manufac ture and susceptible ofbeing assembled into the wall construction with a minimum handhn'g and a minimum expenditure of' labor.

Other objects and advantages of the inventlon reside in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully particularly pointed out in the appended c aim, reference being had to the accompanying drawings forming. part of this specification, and in which:

Figure 1 is a perspective view of a portion of 'a wall embodyingthe invention;

Figure 2 is a side elevational view of the tile embodied in the wall construction shown 1n Figure 1;- a

'Figure 3 is a plan view thereof. Referring to the drawings it will be see the invention contemplates a composite wall construction which mcludes in all of its embodiments, a brick facing designated genorally at F and preferably comprising or dinary courses 5 of facing brick, having at. regular intervals, preferabl atevery sixth course, header bricks 6. ile, designated generally at 7, is associated with the brick facing and in all forms of the invention is so constructed and arranged as to form with the brick facing. an or a-nized wall The facing brick, the tile,

and the tile and the facing brick are bound together in the usual manner by mortar or the like M. a I

Referring especially to Figures 1, 2, and 3, the tile T which enters into the wall construction in this embodiment of theinvent-ion consists of relatively. large rectangular blocks 7 of cellular construction and embodying vertical webs defining an inner series of vertical openings and an outer series of vertical openings, designated at 8 and 9, respectively, -The blocks 7 are preffive ordinar courses'5 of the buck facing and these books are arranged ina coursead acent and immediatel to the rear of the .erably of a height equal to the height of the llhe tile T includes shoulders or rela-- tively small block portions 10 arranged adacent and immediately to the rear of the 'header courses 6 ofthe facing brick. The

of one course of the tile are alinedwith the openings 8 and 8 of the adjacent courses so as to provide continuous air passages through the wall. Moreover the vertical webs of which the blocks of the courses are constituted are also alined so that the webs of the blocks of one course are superposed on the webs of the blocks of the lower course and in this manner the full load bearing strength of the burned clay comprising the tile is utilized. The header bricks 6 extend in between the ends of the blocks 7 and have their inner ends spaced from the relatively small block portions 10 to provide a gap A andto complete the organization of the wall construction.

It is thus seen that the construction and arrangement of the tile and of the brick facing is such that the tile and thebrick facing are highly organized and bonded to constitute a strong and durable wall construction. The organization is such that continuous air passages are provided which serve to arrest the progress of any moisture which finds its way into the Wall and preeludes the moisture from penetrating the wall into the interior. The moisture is taken up bythe air in the openings and dissipated in this manner. And again in all of the ock-7 at the rear of the block.

of the large blocks and the was es embodiments of the invention the webs which constitute the tile construction are alined and superposed so that the positive full or maximum load'bearing strain of the burned clay constituting the tile is taken advantage of and no portion of the tiling constitutes a dead load or weight which must be supported bythe steel framework.

1 claim: p

A composite brick and tile wall construction comprising in combination witha brick facing having ordinary courses and header courses, courses of tile including relatively largelblocks arranged adjacent the ordinary courses and constructed of vertical webs defining inner and outer vertical openings, said header courses of the facing extending over the ends of said relatively large blocks and overlapping the outer' vertical openings thereof and terminating short of the inner vvertical openings, said large blocks having relatively small block portions at one end disposed behind the header courses and spaced therefrom and comprisinginteg'ral extensions of vertical webs of said large blocks, said web extensions defining vertical openings, the vertical openings of the relatively small block portions being alined with the inner vertical openings of the relatively large blocks, and the inner vertical openings vertical open: ings of the small block portions being in open and direct communication to define 4 continuous air passages through said walls whereby passage of moisture entirely through the wall is prevented and-the moisture is dissipated.
